A description of the method and the apparatus for automatically controlling the period of a reactor having a movable control rod to vary the output of the reactor is presented. The method and apparatus consists of a detector disposed in the radiation field of the reactor and movable along a path which is directed to provide radiation intensities which decrease approximately exponentially with increasing distance from the reactor. There is a servomechanism for moving the detector aleng the path. There are means for operating the servomechanism to effect movement of the detector at a predetermined constant speed. There is also a source of a constant demand signal and a reference circuit means substracting the output signal of the detector from the demand signal and producing a differential control signal corresponding to any difference between the output and the demand signals. There is also a servomechanism for moving the control rod of the reactor in response to the control signal so as to adjust the output of the reactor in the sense for equalizing the output signal of the detector witb the demand signal, whereby the reactor period is made to correspond to the speed of the movement of the detector.
